Make use of GCD Calculator to determine the Greatest Common Divisor of 215, 713, 261, 981 i.e. 1 largest integer that divides all the numbers equally.
GCD of 215, 713, 261, 981 is 1
GCD(215, 713, 261, 981) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 215, 713, 261, 981 is 1
GCD(215, 713, 261, 981) = 1
Given Input numbers are 215, 713, 261, 981
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 215, 713, 261, 981 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 215, 713, 261, 981 is 1.
Therefore, GCD of numbers 215, 713, 261, 981 is 1
Given Input Data is 215, 713, 261, 981
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 215 is 5 x 43
Prime Factorization of 713 is 23 x 31
Prime Factorization of 261 is 3 x 3 x 29
Prime Factorization of 981 is 3 x 3 x 109
The above numbers do not have any common prime factor. So GCD is 1
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(215, 713) = 153295
GCD(215, 713) = ( 215 x 713 ) / 153295
GCD(215, 713) = 153295 / 153295
GCD(215, 713) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 261
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 261) = 261
GCD(1, 261) = ( 1 x 261 ) / 261
GCD(1, 261) = 261 / 261
GCD(1, 261) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 981
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
GCD(1, 981) = 981 / 981
GCD(1, 981) = 1
GCD of 215, 713, 261, 981 is 1
